New Delhi: The Congress Working Committee met on Wednesday and interim party president Sonia Gandhi, after more than two hours of deliberations, demanded that Home Minister Amit Shah resign following his "colossal failure" in controlling violence in north-east Delhi. "After reviewing the situation, the CWC is firmly of the opinion that what happened in Delhi is a colossal failure of duty for which the Central Government, in particular the Minister of Home Affairs, must bear full responsibility, and calls on the Minister of Home Affairs to issue his resignation immediately. "The Chief Minister and the Delhi Government are equally responsible for not activating the administration to reach out to the people to maintain peace and harmony". she said.
